Cooling towers cool water produced by industrial processes, such as chemical and food processing. Each cooling tower uses a single, two-speed, or variable speed fan to pull warm air out of the water, allowing it to evaporate into the atmosphere. Cooling towers can consume a lot of energy, prompting many facilities to seek energy-saving solutions. Efficient management of these systems can lead to significant cost savings and improved operational performance.

Controlling Cooling Tower Fan Operation with Electronic Temperature Controllers
With single or two-speed fans, an electronic temperature controller can manage fan operation effectively. By sensing the ambient temperature with the NTC sensor, users can set the desired temperature for fan activation using a single-stage temperature controller. For a two-speed fan, the NTC sensor can trigger the low-speed motor and, if the temperature continues to rise, switch to the high-speed fan using a two-stage temperature controller. This precise control optimizes cooling tower efficiency, ensuring that the system operates only when necessary and reducing unnecessary energy consumption.
Alternatives to VFD Solutions
Many recommendations in the market suggest using Variable Frequency Drives (VFD). While VFDs are effective, they can be costly and may not save as much energy as on/off temperature control. On/off temperature controllers provide a straightforward and cost-effective alternative, allowing facilities to achieve energy savings without the high initial investment associated with VFDs. By utilizing on/off control, facilities can maintain efficient operation and extend the lifespan of their cooling tower components.
